Bounding Box Issue using L1/2 browser

Hi, I'm looking into the effectiveness of different satellites of capturing ocean color at local scales. I've been creating spatial subsets in SeaDAS to get a closer view at local coastlines. However, even when using the exact same geospatial coordinates, sometimes the bounding box does not represent the same area. I'm attaching an image for context. The change was more gradual than shown here, but this just represents the extreme. The first is accurate, and as I went through images (I'm going chronologically) the change became more apparent. Does anyone have an idea of why this might occur? Please let me know, thanks!

Are you asking a question concerning the bounding box issue with the subsetting or a question about the gradual change of chlor_a of the Hawkeye data as you asked in the other posts? --

As I mentioned in the other posts, it's helpful that you provide the file names and attach the images instead of PDF files...

The link you provided shows nothing. Judging from the parameters in the link, your search returns two scenes -
SEAHAWK1_HAWKEYE.20210929T183752.L1A.nc
SEAHAWK1_HAWKEYE.20210929T183752.L2.OC.nc (You probably downloaded L2 files)
SEAHAWK1_HAWKEYE.20220904T183758.L1A.nc
SEAHAWK1_HAWKEYE.20220904T183758.L2.OC.nc
L1/2 browser is not mapped. When you enter the coordinates for the bounding box, the browser will return scenes that meet the search criteria. Those scenes will not have the exact coordinates of the bounding box you provided.

That helps, thanks!
